4.1.5 Alignment Jig
To position the telephone handset correctly within the handset positioner cradle, an alignment
jig is supplied (see Fig.4.1). This table top instrument allows you to accurately fix the position
of the telephone handset’s ECRP and then position the handset in the cradle so that the
telephone handsets ECRP lies on the HATS ERP axis when mounted together with the rest of
the handset positioner.
4.2 Mounting and Calibration (Right Ear)
Note: You can order the mounting and calibration of Type 4606 on HATS from the factory as
service 4606- TCF.
This procedure is performed to correctly mount Type 4606 on HATS for measurements on the
right ear (see Fig.4.8 and Fig.4.9). The same procedure can be used for the left ear, taking care
to reverse the position of Support Arm UC-0220 on the ear brick (see Fig.4.7), and the position
of the cradle positioner on the mounting bracket. The two joints on the positioner assembly
should also be adjusted to their “left-hand” positions.
